1988 Buick Lasabre hesitation

[Kevin06082]

Hey all,

My first post so I hope I am doing this right. Anyway, I need some expert help. I just bought a 1988 Buick Lasabre (all the money we have in the world). Upon bringing it home, it really started hesitating after it was warmed up. I would idle rough a little at a red light or a stop sign and when I would try to go it would hesitate a lot. It would go but very slow for a bit then eventually would reach normal speed with a lot of "bucking" and hesitation. The "Service Engine Soon" light also came on. I am just praying that this is not a big deal and was looking to you all for help and suggestions!!! If I am lucky, it will only be a fuel filter or spark plugs. I don't know a whole lot about cars. I sure wish I did.

Thank you all in advance!!!

I suspect you have a bad engine control sensor as the check engine light is coming on. You need to download the diagnostic codes in the computer to lead you to which one is having a problem.

The following link tells how to pull the computer codes off GM vehicles and decode them:
